United rates 3,605,546 CARRYING CARTON Stuart P. Sanford, West Grange, N.J., assignor to Westinghouse Electric Corporation, East Pittsburgh, Pa., a corporation of Pennsylvania Filed Nov. 4, 1957, Ser. No. 694,366 6 Claims. (ill. 206-65) This invention relates to containers and, more particularly, to a carrying carton adapted to compactly unitize a plurality of articles for shipment and sale and thereafter attractively display and render them conveniently portable by the purchaser.

In the shipment and merchandising of certain types of goods, especially those of small size which are purchased in groups rather than singly, it has been found desirable from both a handling and sales standpoint to combine a number of the articles in a suitably designed wrapper or container and thus provide an aggregative unit or so-called pack. Unitized packaging of this character has been extensively adopted in the electric lamp industry for lamp types which are generally purchased in lots by the customer, such as photoflash lamps for example. It has accordingly become standard practice to insert a readily saleable number of photoflash lamps in a suitably apertured platform which holds the lamps in planar base-to base relation and then slip the entire assembly into a tightly-fitting sleeve of corrugated packaging material to provide a flat multi-lamp pack of convenient size. Should the customer desire to purchase a greater number of lamps than that contained in a single pack he is obliged to purchase a number of such packs thereby necessitating the expenditure of additional time and material by the dealer to wrap or otherwise package them.

There is a need, therefore, for a carton which will not only hold a plurality of items having substantially flat surfaces such as multi-lamp packs but which is of such construction that when loaded it can be readily and compactly stacked for bulk shipment to and shelf storage by the retailer and thereafter conveniently conditioned to render the articles portable by the consumer without the need of further packaging. It would also be a definite advantage from an advertising and sales-promotional standpoint if the packaged articles could be exposed to the view of prospective buyers by the retailers to provide an attractive display, if desired, and when being carried by the purchaser.

It is accordingly the general object of the present invention to provide a container adapted to receive a plurality of articles and retain them in convenient shipping and carrying arrangement with a minimum amount of packaging material and a maximum degree of viewability.

Another object of the invention is the provision of an improved carrying carton whereby a plurality of articles may be economically and compactly unitized for bulk shipment, storage and sale and upon receipt by the retailer attractively displayed to prospec ive customers, if desired, and rendered conveniently portable when sold.

A more specific object of the present invention is the provision in an open-ended carrying carton of contentretaining means which may be conveniently and economically formed as an integral part of the carton and easily or automatically disposed to interlockingly engage the edge of a smooth-surfaced article when the carton is set up for loading.

The aforesaid objects, and others which will become apparent as the description proceeds, are achieved by providing a collapsible open-ended tubular casing r sleeve of relatively stilf sheet material having marginal edge portions that are disposed to serve as content-retaining means, and a central portion designed to be conveniently displaced 3,605,546 Patented Oct. 24, 1961:

from the body and contour of the carton and locked in upstanding relation to provide a handle and leave an attractive display window.

FIG. 14 is a view corresponding to that shown in FIG. 5 but illustrates the manner in which the alternative form of carton contemplated by this invention folds flat for bulk shipment.

While the invention may be advantageously employed to compactly and portably unitize any group of articles suited to this type of handling and merchandizing, it is especially adapted for use in packaging electric lamps such as a plurality of photoflash lamp packs or individually packaged, photoflood lamps and the like which while relatively bulky are light in weight.

Referring now more particularly to the drawing, in FIG. 1 there is shown a carrying carton A according to one form of the invention which carton comprises generally an open-ended sleeve or tubular container of rectangular configuration having an integral handle assembly 44- and inturned marginal tab-like members or flaps 28, 30, 32 and 34 at each end thereof which serve as content-retaining elements. The carton A may be conveniently fabricated from a single piece of substantially rigid sheet stock, s ch as paperboard or the like, that has been cut and scored to form a generally rectangular blank 16 of the character illustrated in FIG. 4. As will be seen from the drawing, the blank 16 is divided by a series of transverse and parallel spaced score lines 19 described. The sides of the connecting panel 18 may be similarly mitered and the panel coated with suitable adhesive, as shown in FIG. 4, to facilitate the assembly operation.

The side or peripheral edge portions of the abovementioned wall-forming panels 26, 22, 24 and 26 are further divided by longitudinal cut-and-score lines 29 and centrally-located V-shaped notches 31 into a series of marginal tabular members or flaps 28, 30, 32 and 34 referred to above. The foregoing cut-and-score lines 29 are desirably formed by alternately slitting and scoring the blank material along a line whichparallels th'e'side ofthe blank 16 and connects the points at each corner thereof where the mitering begins so that the marginal flaps thus defined are of substantially equal depth or width. The V-shaped notches 31 are coincident with and symmetrical about the transverse score line 19 joining the top wall 22 with the side wall 24 and of sufficient depth that they bisect the aforesaid marginal tabular portions thereby dividing said portions into four continuous and separately-foldable flap elements 28--30 and 32-454 which each include a comer-forming section of the blank 16.

To facilitate carrying the loaded carton a centrally located handle assembly 44 is provided. As shown in FIG. 4, this assembly is formed from medial portions of the blank 16 and comprises, in general, matching gripforming portions 46 and an anchoring portion 48 defined by weakened or perforated tear lines 43 and 47, respectively. The anchoring portion 48 as here shown is hat-shaped to provide three tabular extensions and constitutes a centrally-located upper segment of the side Wall 20. The grip-forming portions 45 are formed from two adjoining and similarly shaped sections of the side wall 20 and top wall 22 which sections are symmetrical about the score line 19 joining said walls and foldable therealong into overlapping relation. The connecting parts of the grip-forming portion 46 within the top wall 22 and furthest removed from the said score line 19 taper inwardly toward eachother and terminate abruptly in transverse outwardly-extending recesses thereby form ing two pairs of ear and slot elements 52 and 54, respectively, in the top wall 22 at the marginal edge por tions thereof located at the base of the grip-forming portion 46. The center of the grip-forming portion 46 struck from the top Wall 22 is removed to provide a D-shaped handle aperture 50 of approximately the same size as the crown of the hat-shaped anchoring portion 48 struck from the side wall 29 thereby enabling said grip-forming portions to be grasped when folded in overlapped relation as hereinafter described. Score lines 55 at the root of the grip-forming portion 46 struck from the top wall 22 serve to hingedly connect the handle assembly 44 to a medial portion of said top wall, preferably along the centerline thereof. The anchoring portion 48 is similarly hingedly connected to the gripforming portions 46 by means of score lines 51 which parallel the aforementioned score lines 55. Thus, an integral handle assembly 44 is provided which is easily displaced from the blank 16 and conveniently foldable into an upstanding two-ply handle which extends longitudinally of and is centrally-located with respect to the top wall 22.

In assembling the carton A according to this embodiment of the invention, the blank 16 shown in FIG. 4 is progressively folded along the transverse score lines 19 and the upwardly-facing marginal end portion of the bottom wall 26 secured to the underside of the connecting panel 13, as viewed in the drawing, to form the collapsi ble open-ended tubular container or sleeve illustrated in FIGS. 1, 2, 5 and 6. The seam or joint thus extends along the bottom of the carton A enabling the side and top walls thereof to be neatly and conveniently imprinted with informative or decorative matter. The ends of the blank 16 may be fastened together by means of staples or with suitable adhesive, as here illustrated, or the edges of the bottom wall 26 and the side wall 20 may be secured in abutting relation by a piece of gummed tape, in which case the connecting panel 18 may be dispensed with. The opposing walls are preferably of the same size and contour so that the carton A may be collapsed flat for bulk shipment from the supplier to the user, as illustrated in H6. 5, the carton as here shown being collapsed so that the bottom wall 26, side wall 20 andthe juncture sea-m therebetween face upwardly as would be the case if the blank 16 were assembled by automated means well known in the art. It should be noted that the handle assembly 44 remains connected to and within the contour of the wall-forming panels of the blank 16 from which it is struck thereby permitting the cartons to be tightly' packed for bulk shipment to the user and (after being loaded) to the retailer.

To prepare or set up the carton A for loading it is 7 first distended from its as-received collapsed condition 7 (FIG. 5) into tubular formation, as shown in FIG. 6,

and the marginal flaps 2830 and 32-34 folded inwardly along the cut-and-score lines 29. This operation may be most conveniently effected by slightly collapsing the carton A along the notched score line 19 and the one diagonally-opposite thereto and then pressing the flaps inwardly at the scored corner forming portions thereof to thus snap them into the carton from their normally longitudinally-extending position, as shown in FIG. 6, to their operative inturned position illustrated in FIGS. 1 to 3 and 7 to 9. The carton A is then returned to its fully distended position and generally rectangular shape shown in FIGS. 1, 2 and 6, thus completing the setting-up operation; It will be noted that when set up in this fashion diagonally opposite corners at each end of the carton A are slit by V-shaped notches 31 and 39, respectively, the first mentioned being the V-shaped notches described above and the latter being formed by the mitered corners of the blank after it has been assembled into tubular formation. The marginal flaps 28-30 and 3234 by virtue of their continuity and the fact that they each include a corner are locked in their inturned position within the assembled carton A and, due to the stiffness of the blank material, the parts of said flaps remote from said included corners resiliently spring away from their respective conjoined walls to form inwardly protruding retaining elements which features and relationships can best be seen in FIG. 3. Inasmuch as the aforementioned marginal flaps are coextensive with the peripheral edges of the carton A, this form of construction is ideally suited for holding (see FIG. 2) a plurality of vertically-stacked articles 62 having flat surfaces, such as a plurality of generally flat and rectangular photofiash lamp packs or the like. It will, of course, be understood that the wall-forming panels of the carton A are suitably dimensioned in cross-section to snugly receive the articles 62 when the latter are arranged in loaded position. This dimensional relation and the manner of loading is illustrated in FIG. 2 and in FIGS. 7 through 9, the latter being fragmentary top sectional views of the assembled carton A shown in FIGS. 1 and 2.

As illustrated in FIGS. 7 through 9, as each of the articles 62 is longitudinally inserted into the carton A the inturned marginal flaps (flaps 28, 32 and 34 as here viewed) at that end of the carton are depressed by the sides of the article and compressed flat against their conjoined wall-forming panels (side walls 20 and 24 and bottom wall 26, respectively). The articles 62 are forced inwardly until they contact the protruding flaps (members 28, 32 and 34 as viewed in the drawing) at the opposite end of the carton A whereupon the flaps at the loading end spring away from their respective walls to provide an inwardly-protruding peripheral lip or flange which engages the outer edge portions of the articles 62 and locks said article in loaded position within the carton A.

As shown in FIG. 9, the overall length L1 of the carton A is such that the reduction thereof effected by the combined widths of the inturned content-retaining flaps 28-30 and 32-34 at each end provides an article-receiving space or loading length which is just slightly longer than the length L2 of the articles 62 to be accommodated. Conversely, the width of the opening W1 defined by said flaps when in their inturned positions is considerably less than the width W2 of said articles and (as shown in FIG. 2) substantially shorter in height than the combined height of an integral number of verticallystacked articles, for example five as in the case here illus t-rated. In this manner the articles 62 are individually and collectively snugly received by and looked within the carton A. The content-retaining flaps 28-456 and 3234 by virtue of their continuity, rigidity and snappedinturned relation with the main body portions of the carton A provide depressible cleats or lips which (i) not only bear against the peripheral end edges of the stacked articles 62 in line contact therewith and prevents them from accidently falling out of the carton A when the latter is being carried but are (2) capable of being subsequently flipped into longitudinally-extending position (as shown in FIG. 6) to permit one or several of said articles to be conveniently withdrawn for use and (3) thereafter snapped back into the carton to retain the rest of the articles in their loaded positions as before.

Turning now to the handle assembly 44, after the carton A has been loaded as above-described and shipped to the retailer or subsequently sold, the matching grip-forming portions 46 and anchoring portion 48 are conditioned for use by simply displacing them from the top wall 22 and side wall 20 by separating the blank material along the weakened tear lines 43 and 47, respectively. The handle assembly 44 is then manipulated so that the gripforming portions 46 are folded one upon the other in overlapping relation along the transverse score line 19 joining said top wall 22 and side wall 20 and the anchoring portion 48 disposed in planar relation with the side wall 20 and slipped between the inside surface thereof and the loaded articles 62 toward the top wall 22. In this manner the grip-forming portions 46 are progressively flattened one against the other during which time the anchoring portion 48 is maneuvered into planar relation with the top wall 22, as illustrated in FIG. 6.

Further displacement of the handle assembly 44 in the direction indicated in FIG. 6 forces the straight outwardly-facing edges of the gripforrning portion 46 struck from the side wall 20 to ride over the ears 52 provided in the top wall 22 and snap into the recesses 54 therebehind thus completing the operation and locking the handle assembly 44 in upstanding operative relation, as illustrated in FIGS. 1 and 2, due care being taken during this phase of the operation to slide the crown-like tabular eX- tension of the hat-shaped anchoring portion 48 under the top wall 22. This latter interleaving arrangement in conjunction with the correspondingly disposed brimshaped extensions not only serves to reinforce the top wall 22 but distributes the loading stress imparted thereto by the handle over a considerably greater area thus greatly increasing the load carrying capacity of the carton A. As will be obvious, the configuration of the anchoring portion 48 may be altered to enlarge its contacting area and distribute to an even greater degree the stress on the top wall 22 thereby proportionately increasing the rupture strength of the material. With the handle assembly 44 thus locked in upstanding position, an attractive display window 60 (FIGS. 1, 2 and 6) is provided through which the contents of the carton A may be viewed. This latter feature in conjunction with the openend type construction employed provides in a very economical manner maximum viewability of the contained articles in the event the carton A is utilized as a display device and, in any case, when being carried by the purchaser. The handle assembly 44 is also capable of being retracted back into the contour of the cartonA, if desired, by springing the grip-forming portions 46 from their-interlocked relation with the ear and recess elements 52, 5-4 and simply reversing the procedure outlined above. Thus, the handle assembly 44 by virtue of its ability to be simply and conveniently disposed in operative position after loading preserves the rectangular contour of the cartoirpermitting it to be compactly loaded for bulk shipment to and storage by the retailer,

In FIG. 10 there is illustrated an alternative form of the invention wherein a carton B of the same general configuration as carton A is provided. According to this embodiment, however, the blank 16a (FIG. 13) is divided by means of transverse score lines 19a into a series of rectangular panels proportioned to serve as a top wall 22a, side walls 20a and 24a and a pair of end panels 62 and 64 which, when joined together, form the bottom wall. With this type construction the juncture seam extends along a medial part of the bottom wall, as illustrated in FIGS. 10, 11 and 14, thus facilitating the manufacture, printing and assembly of the blank 16a by automated boX-making equipment well-known in the art. Each side of the blank 16a is longitudinally divided in this case by score lines 63 and V-shaped notches 65 provided at alternate ones of the aforementioned transverse score lines 19:: into separately foldable marginal flaps 66, 67 and 68. The V-shaped notches 65 (as shown in FIG. 13) are coincident and symmetrical about the transverse score lines 19a which join the top wall 2211 with the side wall 20a and the other side wall 24a with the adjoining end panel 64. A plurality of triangular-shaped recessed webs 72 are provided in the flaps 67 and 68 at the ends of the other of said transverse score lines 19a by appropriately notching and scoring the material thereat to form a plurality of truncated V-shaped notches 70 and paired outwardly-diverging score lines 71, the latter forming continuations of the sides of said notches and meeting at the aforementioned longitudinal score lines 63. Inasmuch as each of the above-described Web structures are identical, only the divergent score lines 71 in the upper marginal flap 68 of the blank 16a, as viewed in FIG. 13, have been identified by reference numeral. Only those sections of the marginal flaps 66, '67 and 68 which project beyond the line connecting the peripheral edges of the webs 72 are coated with suitable adhesive material so that the desired result hereinafter described may be obtained.

A handle assembly 44a comprising a hat-shaped anchoring portion 48a and matching grip-forming portions 46a is struck from the side Wall Zoo-and top wall 22a and rendered foldably displaceable therefrom by suitable tear lines 43a, 47a and score lines 51a, 55a in the same fashion as described above in connection with carton A. Bar and slot elements 52a and 54a are also provided in the top wall 22a at the base of the grip-forming portion 46a struck therefrom to lock the handle assembly 44a in upstanding position as before. According to this design, however, instead of removing a part of the grip-forming portion 46a struck from the top wall 22a to form a handle aperture, a tear line 73 is provided (see FIG. 13) which, when said grip-forming portion is disposed in operative position, provides a handle aperture 50a as before and leaves-a similarly shaped tongue 74 projecting from said wall, as shown in FIGS. 10 and 11.

Assembly of the blank 16a according to this-form of invention is elfected by first folding the marginal flaps 66, 67 and 68 downwardly, as viewed in FIG. 13, into spoasae inturned overlapping relation with the corresponding adjoining wall-forming panels of the blank and securing shown in FIGS. l0, ll, 12 and 14. The blank 16a is then progressively folded, as in the case of carton A, along the transverse score lines 19a and the upwardly-facing marginal end portio'n of the end panel 62 secured to the underside of the adhesively-coated tabular part of the other end panel 64, as said panels are viewed in FIG. 13, thus forming a tubular open-ended sleeve as before. The application of pressure along the transverse score lines 19a provided with the V-shaped notches 65 collapses the carton B thus formed rendering it ready for bulk shipment to the user, as illustrated in FIG. 14 (the carton B as here illustrated being rotated through an angle of 360 from itsas-assembled position after completion of the foregoing folding operation on the blank 16d when thelatter is disposed as shown in FIG; 13). a

An important feature according to this embodiment of the invention is the construction and'mode of operation of the content-retaining means. As stated above, the triangular-shaped webs 72 are purposely left unattached and are defined by pairs of appropriately oriented score lines 71. In the assembled carton B these webs by virtue of the foregoing construction and manner of assembly constitute collapsible gussets at diagonally-opposite corners at each end of the carton B. When the carton B is distended into tubular formation preparatory to loading (seetFIGS. and 11), the rigidity of the blank material and the manner of scoring causes the gusset-forming webs 72 to automatically spring away from the walls and protrude inwardl which characteristic can best be seen in FIG. 12, thereby forming dcpres-sible content-retaining elements adapted to engage diagonally-opposite corner edge portions of a rectangular-shaped and slightly undersize article 90, a's shown in FIG. 11. Since the aforesaid content-retaining elements are located at oppositely-disposed corners only, this construction (in contrast to the marginal flap arrangement described in connection with carton A) effects what may be termed point retention so that the articles must be arranged in double layer and preferentially single layer formation. This manner of retention can, therefore, be most advantageously employed when the articles to be unitized are more or less cubical in form and lend themselves to horizontal rather than vertical stacking, such as a group of incandescent lamps of the photoflood type, for example, which lamps are individually packed in cubical paperboard containers. As will be appreciated, the loading length of the carton B is so proportioned that an integral number of such articles can be snugly accommodated therein between the aforesaid webs 72 when the latter are in distended position. It will, of course, be obvious that when the carton B is cross-sectionally dimensioned to snugly receive a single row of articles, one such comer-gripping element at each end of the carton would be sufficient to retain the articles in their loaded position, but at least two such elements at each end and atdiagonally-opposite corners, as here illustrated, are preferred.

The handle assembly 44:: is conditioned for use in the same manner as in carton A, the only difference being that the tongue 74 left in the top wall 22a extends into superimposed and edge-coinciding relation with the anchoring portion 48a, as illustrated in FIGS. 10 and 11, thus affording a greater area of overlap or interleave between these elements and even further strengthening the top wall 22a against rupture without the utilization of any additional material. As in the case of carton A, disposure of the handle assembly 44a in operative position provides an attractive display window 60a into the interior of the carton B, as shown in FIGS. 10 and 11.

As will be obvious from the foregoing, the objects of the invention have been achieved by providing an openended carrying carton adapted to compactly utilize a plurality of articles and form a merchandizing unit which may be readily shipped, stored and attractively displayed and by providing integral content-retaining and handle means for such a carton capable of being quickly and simply assembled to render said articles conveniently portable by a purchaser.

While the present invention has been described in some detail by way of illustration and example for purposes of clarity of understanding in accordance with the patent statutes, it is understood that various changes and modifications may be made without departing from the spirit and scope of the invention. For example, while the articles have been illustrated and described as being rectangular in form, cylindrical shaped articles such as cans or bottles or the like and other items of non-rectangular configuration may be packaged in accordance with the principles of the invention by suitably proportioning the walls of the carton and contouring the content-retaining elements to snugly receive said articles when in vertical or horizontal stacked relation and abuttingly engage the outwardly-disposed peripheral edges thereof.
